So sorry to ask this question again and again, but it really bothers me
very much.
Now I debugged into hpcInit.c and open(devcie)  returned successfully,
where the device is /dev/ttyE0
But the call to OpenFrameBuffer() failed. It failed at
    ioctl(fd, WSDISPLAYIO_SMODE, &mode) returned -1;
I think this call had not stepped into my LCD driver because my lcd_ioctl
only returns EPASSTHROUGH(-4) instead of -1.
It looks like the wsdisplay driver was not conigured correctly. Anybody
can tell me the possible reason that will result in ioctl calling failed? Or
need to change my kernel configuration?
